FLOAT-CONTROLLED Application filed April 26,

To all whom it may concern Be it known that I, Awnnnw MOSEGARD, a citizen of the United States, residing at Morgan Hill, in the county of Santa Clara and. State of Oalifornia, have invented cer tain new and useful improvements in Float- Controlled Circuit-Breakers, of which the following is a specification.

This invention relates to improvements in float controlled circuit breakers.

The invention has for its object to provide for automatically indicating the need of the replenishing of the water supply used in producing a cooling action upon the engine, as in maintaining the requisite height thereof to guard against burning out of the engine.

A further object is to provide for stopping the running of the engine upon the water reaching the low water-mark, accordingly guarding against the running of the engine in the absence of the cooling action of the water, the cause of the burning out of engines of this type.

A still further object is to carry out the aforesaid ends in a simple, inexpensive and effective manner and with facility.

The invention therefore consists of certain structural features including the combination and arrangement of parts substantially as hereinafter disclosed and defined by the appended claim.

In the accompanying drawings is illustrated the preferred embodiment of my invention, and wherein it will be understood that various changes and modifications as to the detailed construction and arrangement of parts may be made Without departing from the spirit of the invention, and in which drawing Figure 1 is a perspective view of my invention. Fig. 2 is a sectional elevation of the water-tank showing my invention in side elevation in connection therewith, the latter also being shown in certain dotted line positions. Fig. 3 is a detailed side view of the magneto switch lever. Fig. 4 is a detailed perspective view showing more particularly the connection between the float-valve stem and the water-tank containing the float valve.

In carrying out my invention, I provide, in connection with an ordinary water-containing tank 1 having a valved intake pipe at and a valved water delivery pipe I), a float or valve 2 having its stem or rod 3 Specification of Letters Patent.

CIRCUIT-BREAKER.

pivotally connected, as at 4:, to the inside of said tank, near the upper edge thereof, said float or valve being borne upon the watersurface and of course, controlled by the action thereof. Said float or valve stem 3 has loosely sleeved or carried thereon, a tubular member or sleeve 5, which sleeve is slidable upon said rod or stem, and has flexible or chain-connection 6 with a switch lever 7 for controlling the ignition circuit of the engine, the ends of the chain or flexible connection being connected to the stem 7 of said lever and the distant end of the tubular member or sleeve, respectively, as clearly seen in Figs. 1 and 3. Said sleeve or tubular member 5, it will be seen, is of a relative length with respect to the float stem or rod 3 and so positioned initially thereon as that, when the latter is in horizontal position, and the water-level accordingly at its maximum height, as indicated in Fig. 1, one end of said stem or rod will be distant from the pivotal connection between said stem or rod and the tank, whereby when the water level lowers by the gradual evaporation of the water, the chain or flexible connection 6 will draw upon and gradually move the sleeve upon the float-stem or rod 3, which drawing action of the chain upon the sleeve will continue as the float-stem descends with the continued fall of the water from evaporation, the sleeve at a certain interval contacting with the point 4, as for instance, as indicated by the upper dotted line showing. At this juncture, the sleeve will offer resistance to the chain or connection 6, as is apparent,

and accordingly transmit the pull through the sleeve and effect the actuation of the switch-lever 7 connected in electric circuit with the magneto with the further descent of the water until the float valve has reached its maximum descent or the low-water mark, as for instance, as indicated by the lower dotted line showing, the switch lever by that time having been moved out of normal contact position, thus breaking the circuit established by the magneto 7 wired as at 7 c with the battery 7 and said switch-lever and its contact member 7 accordingly providing for the stopping of the engine.

Upon replenishing the water-supply to the tank 1, the float or valve will rise therein and provide for reestablishing the electric-circuit by the pulling of the lever 7*" into engagement with its contact 7 thus putting the engine in operation, the Water being, in the first instance, supplied to the tank 1, and the water supply subsequently replenished via the pipe a, the water being delivered from the tank via the pipe 6 for cooling the engine, as well understood.

I claim:

A float controlled circuit breaker comprising a float, the position of which is determined by the level of the liquid in the supply tank or reservoir, said float being carried by a rod or stem pivoted to the supply tank, a switch, and means permitting lost motion between the float and the switch, whereby the level of the float may fall a predetermined distance before the switch is opened, said means comprising a sleeve slidably mounted on the rod or stem of the float and a flexible element between the outer end of said sleeve and switch.
